The answer is B, osmosis is the movement of water. Diffusion is the movement to chemicals and molecules.
Both osmosis and diffusion are movement of molecules from a region of higher concentration of the substance moving to lower concentration down the concentration gradient. However, osmosis is only for the movement of water molecules, while diffusion is for any type of substances including liquid or gas. So we can also say osmosis is a type of diffusion actually.
And also, both of these movement of molecules does not require extra energy, they all happen due to natural tendency.
Answer: true
Explanation: This is because the outer planets are in a gaseous state while the inner planets are solid and more compact. Consequently, the density of the inner planets is greater than that of the outer planets. Despite the density differences, the mass is smaller for the inner planets than the outer planets.

Answer:
Renewable Energy Resources.
Explanation:
Unlike fossil fuels which cannot be recovered when destroyed, these sources of energy can be recovered by a means of recycling . Recycling here reduces solid wastes which is one of the causes of land pollution.
Hydroelectric schemes can only be built in mountain regions where rainfall and rivers are plentiful which involves upset of aquatic ecosystem. This poses a dangerous pollution problem though.
Wind generators and solar panels are not very efficient energy producers. However, future schemes for producing solar energy via solar satellites are promising.
